Advances in hadrontherapy dosimetry

This paper investigates suitability of two new commercial solid-state detectors as alternative to reference detectors for dosimetry of proton and carbon ion beams, as for scattered and scanned beams.Investigated detectors are PTW microDiamond and PTW PR 60020 diode that have very small measuring volume with extremely reduced thickness of active detector layer (1m for diamond, 20m for diode).Both detectors were tested in 62MeV ocular proton therapy beam (INFN-LNS), PTW microdiamond was tested in clinical scanned carbon ion beams up to 400MeV/u (CNAO), PTW PR 60020 Dosimetry was tested in scanned proton beams up to 250MeV (CNAO).
